how to render individually choicefield in Django

I'm working on models in Django, I have a choicefield in models but I don't know rendering this manually in template, somebody can help me?

Models:

class Plantonista(models.Model): 
    FRESHMAN = 'FR'
    SOPHOMORE = 'SO'
    JUNIOR = 'JR'
    SENIOR = 'SR'
    YEAR_IN_SCHOOL_CHOICES = (
        (FRESHMAN, 'Freshman'),
        (SOPHOMORE, 'Sophomore'),
        (JUNIOR, 'Junior'),
        (SENIOR, 'Senior'),
    )
    year_in_school = models.CharField(max_length=2,
                                      choices=YEAR_IN_SCHOOL_CHOICES,
                                      default=FRESHMAN)

Template:

<div class="mdl-cell mdl-cell--4-col">
    <select class="" name="">
        
    </select>
</div>
